+# This property indicates with what Cassandra major version the storage format
will be compatible with.
+#
+# The chosen storage compatiblity mode will determine the versions of the
written sstables, commitlogs, hints,
+# etc. Those storage elements will use the higher minor versions of the major
version that corresponds to the
+# Cassandra version we want to stay compatible with. For example, if we want
to stay compatible with Cassandra 4.0
+# or 4.1, the value of this property should be 4, and that will make us use
'nc' sstables.
+#
+# This will also determine if certain features depending on newer formats are
available. For example, extended TTLs
+# up to 2106 depend on the sstable, commitlog, hints and messaging versions
that were introduced by Cassandra 5.0,
+# so that feature won't be available if this property is set to CASSANDRA_4.
See upgrade guides for details.
+#
+# Possible values are in the StorageCompatibilityMode.java file accessible
online. At the time of writing these are:
+# - CASSANDRA_Y: Stays compatible with the Y.x line in features, formats and
component versions
